not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2024The c.2840G>A (p.R947Q) alteration is located in exon 16 (coding exon 16) of the FAM184B gene. This alteration results from a G to A substitution at nucleotide position 2840, causing the arginine (R) at amino acid position 947 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
